Machinist{3 s parallels

ABSTRACT

In a machinist&#39;&#39;s parallel, one or more round pockets having preferably a flat bottom and locating a resilient means which is connected preferably to another parallel having same pocket, said parallels keep the set up with precision when used between jaws of a machinist vise or a fixture.

venfor MACHINISTS PARALLELS This invention relates to machinists parallels or blocks or jiffy jaws of a machine tool, vise or fixture which is used for holding firmly a part being machined on. By way of example, standard parallels used up to now have been moving when the machine is vibrating or when the machine operator is cleaning the top surface of the parallels in order to place another piece to be machined; such standard parallels don't stay in position in an angular vise or a compound angles vise. This invention holds firmly the machinist's parallels in proper place against the jaws of: the machine tool vise, angle vise, fixture, etc.

Important objects of the invention is to provide:

a. A resilient means to hold apart parallels, blocks, jiffy jaws, etc.

b. A pocket locator for resilient means.

c. A spring extension to suit greater distances from parallels to parallels.

Other and further objects and advantages of the invention will be apparent from the following description thereof and from the claims appended thereto.

ln the drawings wherein like numerals refer to like or corresponding parts throughout the several views:

HO. 1 is a side view of a portion of an inclined machine vise, showing the invention in position of use.

HO. 2 is a sectional side view of a parallel showing pocket and spring.

1. FIG. 3 is a front view of a parallel pocket.

2. FIG. 4 is a longitudinal view of two springs and spring extension pin assembled.

3. FIG. 5 is a longitudinal view of two springs and spring extension tube assembled.

, Referring to the drawings, the numeral 6 designates but not necessarily another parallel 6 having the same pocket 13. When the distance from parallel is too long and spring 9 too short, a spring extension pin 16 connects frictionally spring 9 to a spring 17, or a spring extension tube connects frictionally spring 9 to spring 19. Said pocket wall 14 and extensions 16 and 18 can have their contact surface knurled, or threaded, or magnetic, as to make a better holding grip.

While the foregoing has illustrated and described what is now contemplated to be the best mode of carrying out the invention, the construction is, of course, subject to modification and improvement without departing from the spirit and scope of the invention. It is therefore, not desired to restrict the invention to the particular forms of construction illustrated and described but to cover all modifications that may fall within the scope of the appended claims.

lclaim:

1. In combination with a machine tool vise having a pair of jaws, a machinist's parallel, a side of said parallel positioned against one jaw of said vise with a resilient means bearing on the opposite side of said parallel and on the other jaw of said vise. l

2. The device of claim 1, further comprising, a pocket having a wall and a bottom locating a resilient means holding apart said parallel from another parallel.

3. The device of claim 2, further comprising, a circular pocket having a wall perpendicular to a surface of said parallel, and a bottom parallel to a surface of said parallel, said pocket nests frictionally the end of a resilient means or spring which is extended to another similar pocket in a similar parallel, and both parallels are pushed and stay against a jaw of a machine tool vise or fixture, no matter what angle jaws are inclined.

4. The device of claim 1, wherein, two resilient means are connected together with a pin fitting frictionally their inside diameter.

5. The device of claim 1, wherein, two resilient means are connected together with a tube fitting frictionally their outside diameter.
